LUBRICVATOR;

Application filed July 2l,

To @ZZ whom t 'may concern:

Beit known that I, THOMAS E. COLEMAN, a citizen ot' the United States, residing Madison, in the cornitysof Dane and' State of YVisconsin, have invented certain new and useful Improvements in Lubr'icators, of which the following is a' specification.

This invention pertains to lubricators and more particularly to that type wherein a regulated quantity of oilv is periodically forced to a plurality of points to be lubricated.

Automobiles in particular, as is well known, require adequate but regulated lubrication, and it is essential that each bearing or part to be lubricated shall receive its proper' quantity of oil.

The present invent-ion has for its main Object the provision of a simple structure whereby such lubrication may be positively efected.

Referringcfirst to theY construction illuslr` trated in Figs. 1 to 9 inclusive, 1 denotesa' suitable oiilreservoir, provided'wi'th a filler strainer 2 extending downwardly from a removable cover, 8. Secured to the under face of the cover andrextend'ing downwardly into the reservoir is a bracket 4t at the lower end of which there is formed a bearing for a hub or' sleeve 6, upony which is mounted andv secured a worin gear 7 designed to be driven by a worm S which in turn is actuated from a moving part of the structure to Y be lubricated. A shaft 9' is supported' at one end in the sleeve 6, the shaft at its opposite end carrying one member 10 of a slidable coupling, the other' member 1.1 be-v ing secured to a stub shaft 12 mounted in the adjacent end wall of the reservoir 1 and adapted to be actuated by hand thro-ugh the medium of av crank or lever 1S.

rEhe inner end of sleeve 6 is provided with 'a projection 14 adapted to ent-er" slot formedl in a hub 15 which ispart of a wobbling eccentric 16` of one ot the pump units hereafter described. Said hub 15 islikewise engaged with a secoi di hub 17 uponwhich is mountedA av wobblfrg eccentric 18 ott' a second pump unit later to be described.' rthe hub 17 in turn is interconnected with a sleeve 19 wliiclrinds its bearingrin a box 20 formedv in. aidownward extension et the distributor casting denoted generally by 21.y

The pumps heretofore referred to are' alike inl forni and operationw andi a' description oi? one will therefore suiice Jfor' both, and' simi-` lar parts will be; similarly lettered. The pump casting is denoted by 22 and. the cylinder thereof' 'is preferably controlil'edr by an adjustable' sleeve 23'r in the manner set forth and 'claimed' ini Letters Pat-entI 1,262,979', dated Apri-l 1G, 1918. 'llhe' pistoni 24 is confnected by a yoke 25 which functions with the wobbling eccentric .16 (012,18*). -rl`he pumpfmay be oft" any approved type, that shown being so; constructed that the piston is osciilflated so as to bring spillrports into registry 'when the piston 'has caused the. discharge of aixed' or regulated quantity et oil; The intafkeof the pump is shown as a pipe 26 that extends down to the low'er por- IDO tion of the reservoir, as best indicatedin Fig. 2. Said pipe 26 is incommunication with an intake port 27 and an exhaust port 28 is located upon the opposite side of the housing 22, a pipe 29 being connectedwith the outlet of said discharge conduit or port 28, extending downwardly and laterally therefrom and being connected to aV port or opening 30 (see Fig. 7) formedin the lower portion of the distributor casting. A similar pipe,`denoted by 29 leads fromthe second pump and is connected to a second opening 30a formed in the lower portion of the casting. A bore or opening is formed in the lower portion of the distributor casting 21, said bore extendingV horizontally therethrough and forming a seat for a rotating distributor element 31, shown-in detail 'in Figs. 8 and 9. One end vof said element is provided with a head 32 which makes a close fitV against the end of the distributor casting while the opposite end of said distributor element 31 is flattened, as at 33, and attached thereto is a star or pocketed ,wheel 34.l A crank 35 carrying a roller or bowl'36 is attachedto the sleeve 19 (Fig. 1) and as the actuating shaft is rotated the arm 35 is moved in the direction of the arrow (Fig. 3) and the actuator or star wheel 34 is advanced step-by-step so as to bring one or another of the ports or passages in the rotary distributing element 3l into line with the distributor conduits or passages 'formed in the casting 21 and the ports or'openings 30, 30a with which the pumps are connected,

as above described. The distributor element 31, in the form where two pumps are employed, is provided with two circumferential grooves or channels 37 and 38, which, when the parts are positioned, are at all times in Ycommunication with the ports 30, 30, yA pair of inclined ports or passages communicate with each of the circumferential grooves or channels 37 'and 38, those communicating with the channel 37 being designated by 39 and 40, while those communieating with the feed channel 38 being designated by 41 and 42. As will be best seen uponreference to Figs. 8 and v9, each pair of inclined channels are similarly, arranged and pass diametrically through the rotatable distributor element31, said chani nels inclining respectively V`to'each side of the feed groove 37 or 38 so that the discharge ends lthereof are spaced apart both longitudinally'and circumferentially of the rotatable element 31.

The casting 21 is provided with sixteen openings in its upper face into which are threaded pipes that extend tothe points to be lubricated. The openings communicate at their lower ends with conduits arranged in bangs of four across the casting (see Fig. 5), an are designated, respectively, by 43, 43a, 43h, 43"; 44, 44, 44h, 44C; 45, 45a, 45h,

conduits.

45C; 46, 46, 46", 46c. In kfact the openings and conduits may be treated as conduits havmg enlarged upper threaded ends. In orlder to facilitate theV formation of the innermost pair of conduits 45a and 45h, and the similarY ones, the casting is bored partially through from below and plugs, as 47, are secured in the lower end of such opening.

As will be seen upon reference to Fig. 5 the discharge Vend ofthe port or passage 39 stands in line with the various'ports 43 to 43C inclusive. rThe discharge opening of the port or passage stands in line with the conduits 44 to 44c inclusive. The discharge end of the port 41 stands in alinement with the conduits 45 to 45c inclusive, while the discharge of the channel 42 stands in alinement .with the `mouths of the conduits 46 to A46v inclusive. The discharge mouth of eachV channel is brought successively into alineme'n'tV with the intake mouth of each conduit ofrthe series which said channel serves,'andthis is effected through the stepby-step rot-ation of the member '31 through the operation of the crank 35 and its roller 36 upon the star wheel 34. VAs will be seen upon reference to Fig. 3, there are eight pockets in lthis wheel so rthat'the distributor 31'isrotated through an angle of `45o and then comes to rest. The parts are so timed that theV pump begins its forcing ystroke,

lthe pipe 29 or 29E-as the case may be, to

the opening 30 or 30 and to the groove 37 or 38 just before the mouth of the channel 39 or 40 (or 41 or 42) comes into alinement with one or another of the conduits 43 et seq.

In Fig. 3 the actuator 35 is about to complete one step in the vmovement of the star wheel 34, and the passage,V (shown in dotted lines in Fig. 6) is about topass out of registry with the adjacent conduit with which it had been in registry, and the other passage shown in full lines) is about to come "into registry with one or the Vother conduit.

In order to prevent any possible overthrow of the distributor 31 and thus carry the ports out of registry I provide animpositive stop Vconsisting of a ball (see Fig. 1) 34E-urged outwardly by a spring 35 seated in rear Vof the ball and in a lpocket formed in the casting 21, the ball functioning with depressions 36?L provided in the adjacent t'ace of the wheel In Figs. 10 and 11 aslight inodilication of the structure is shown. In this instance the distributor is denoted by 31a and is provided with but a single passage leading from each of the circumferential grooves with which the pumps connect. lith such an arrangement each pump supplies four It is conceivable that the eight conduits may be supplied from a single pump, in whichl instance 'the distributor would take the form Vshown in Fig. 12,

llfi

wherein there is but a single circumferential groove with two channels opening there.- into and having their discharge mouths spaced apartin the same manner. as speci.- tied in connection with Figs. 8. and 9. It is manifest, of course, that by employing. a greater or less number of pockets or. openings in the periphery of the star wheel: Si,

and correspondingly forming a greater or the conduits, in which case the other open ing leading from the casting would be plugged or closed. Thus, in Figs. l and 1l, a cross channel 55 is shown, connecting the adjacent conduits, and the oil passing' from the opening 40 would be forced through each of said adjacent conduits as it comes into registry with the mouth thereof. If the outlet for one of the conduits was not closed only a portion of oil would pass through each conduit` whereas if the mouth of one of them was closed the entire charge would pass through the unclosed mouth each time the channel in the rotary distributor came into register with each of the conduit mouths.
